Get more capacity Plug in the additional battery and double RIVER Pro’s capacity to 1440Wh from 720Wh. A great addition if you’re looking to power higher-wattage devices for longer.
Power more devices With RIVER Pro’s X-Boost mode you can power devices up to 1800W. This should cover you for almost all your appliances and some power tools too.
Take power with you Lightweight, compact and complete with a carrying handle, take your extra battery with you with ease. Small enough to store in a garage, fit in the boot of a car or to take with you on a camping trip, you can rest assured you’ll have an abundance of power no matter where you are.
Love this expansion battery. Size is great, power rating is great
I got my River Pro right before Christmas. We travel to my wife's mom's house every Christmas, to join family. Several of us sing and play. Her front porch doesn't have any outlets, but no worry. I brought out my River Pro, plugged in my 75 watt amplifier, and we played for hours. No extension cords to trip over! It was incredible! I love this thing, and so did everyone else. I will tell all my musician friends. A life saver! Well,,,,,not quite, at least in this situation
Lots of extra power. Not as portable like the Delta but great to have
Fast charging, doubles my amount of stored power, reliable.
Outstanding product and excellent customer support.
